Note: If the TFTP IP is changed which is not included in the current Certificate Trust List (CTL) file, then TFTP will fail and

be erased manually in the Security Configuration menu from the Cisco Unified Wireless IP Phone 7925G.

Configuring Advanced Network Profile Settings

In the Advanced Network Profile settings, you can adjust the minimum PHY rate. If 12 Mbps is not enabled in the wireless

LAN, then you may need to configure this parameter or enable 12 Mbps on the access point.

By limiting number of channels to be scanned, this can help reduce the time for access point discovery while passively scanning

DFS channels in 802.11a mode. This can also help preserve battery life.

If using this feature, then only disable those channels that are not used in the wireless LAN. If you disable a channel that is

currently used by an access point, then the Cisco Unified Wireless IP Phone 7925G might not associate to the wireless LAN

successfully.

If all channels that are used in the wireless LAN are disabled on the phone, then use one of these methods to browse to the

Cisco Unified Wireless IP Phone 7925G webpage:

•

USB cable connected to the PC where full web access was previously enabled

•

Re-enable all channels by using the factory default
